Description

Technical Field

[0001] This utility model relates to the field of cold storage ventilation technology, specifically an airflow guiding structure for cold storage. Background Technology

[0002] Cold storage facilities are used for low-temperature storage of goods, and their internal temperature stability directly affects the quality of stored goods. Airflow circulation is a key factor determining temperature uniformity. Most existing cold storage facilities use evaporative air coolers to even out airflow, but unevenness can still occur. Some use ceiling-mounted evaporative air coolers, which draw in air and then deliver it forward using axial flow fans, such as... Figure 1 The airflow pattern of the existing ceiling-mounted air-cooled cold storage shown still has the following technical defects:

[0003] The air cooler's airflow is not flush against the ceiling and wall panels, so heat entering from the outside through the panels cannot be absorbed preferentially. As a result, the heat is directly transferred to the goods, requiring secondary heat absorption by the cold air before refrigeration.

[0004] When goods are stored, they tend to stick tightly to the wall panels, completely blocking the airflow channels on the wall, causing obstructed airflow circulation and creating areas of uneven temperature.

[0005] In addition, the connection between the ceiling, floor and wall panels of the cold storage is a right-angle structure. The airflow flowing along the wall is prone to forming vortices at the right angle, which not only consumes airflow energy and reduces airflow speed, but also causes local heat accumulation and uneven storage temperature.

[0006] These problems not only affect the operating efficiency of cold storage, but also increase the dehydration of goods and reduce the quality of storage. Therefore, there is an urgent need for an improved airflow guidance structure for cold storage. Utility Model Content

[0007] The purpose of this utility model is to provide an airflow guiding structure for cold storage. By improving the structure of key parts inside the cold storage, fluid can adhere to the wall, so that cold air forms an isolation layer between the inner wall of the cold storage and the goods, and absorbs the heat leakage transmitted from the storage panel first.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An airflow guiding structure for a cold storage includes a cold air fan, an arc-shaped plate, and convex strips. The cold air fan is installed in the central area of ​​the ceiling at the top of the cold storage or is evenly distributed along the length of the ceiling, with its air outlet direction parallel to the bottom surface of the ceiling. The arc-shaped plate is installed at the corner of the inner wall of the cold storage, and the convex strips are vertically embedded in the inner side of the wall panel inside the cold storage and are evenly distributed along the height of the wall panel.

[0010] The air cooler's outlet is no more than 5cm vertically from the bottom of the ceiling, ensuring that the airflow directly adheres to the ceiling to form a wall-mounted airflow. It is fixedly connected to a pre-installed mounting bracket on the ceiling using expansion bolts. The mounting bracket is made of stainless steel and is bolted to the air cooler's flange. A sealing gasket is placed between the flange and the ceiling to prevent cold air leakage.

[0011] Furthermore, the thickness of the air cooler is controlled at 10-15cm, the air outlet is set to be flat, the width of the air outlet is adapted to the width of the cold storage ceiling, and the height of the air outlet is 3-5cm, to ensure the formation of a flat, wide, and thin airflow.

[0012] The arc-shaped panel is installed at all corners of the cold storage, including the corners between the ceiling and the wall panel, and the corners between the wall panel and the floor. The panel strip covers the entire corner length and extends to the inner edge of the cold storage door and the rear wall of the cold storage to ensure that there are no blind spots at the corners.

[0013] Connections can be made by welding or bolting. Stainless steel connecting lugs are pre-set on the inner side of the strips. The lugs are welded and fixed to the embedded steel parts of the ceiling, wall panel or floor. The outer side of the strips can be reinforced with stainless steel expansion bolts. The joints of the strips can be welded and sealed with mortise and tenon joints to avoid air leakage or dirt accumulation in the gaps.

[0014] The arc radius of the arc plate is 8-12cm, the plate thickness is 3-5mm, and the surface is treated with a smooth anti-rust coating to ensure smooth and unobstructed airflow.

[0015] The convex strips are vertically embedded in the inner side of the wall panels of the cold storage, and are evenly distributed along the height of the wall panels. The length of the convex strips extends from the floor surface to 3-5cm below the bottom of the ceiling. The spacing between adjacent convex strips is 80-120cm. The protruding direction of the convex strips faces the inside of the cold storage, and the minimum distance between the protruding end and the goods shelf is controlled at 15-20cm.

[0016] The convex strip adopts an integral molding structure, and a slot can be set on its back. The inner side of the wall panel is pre-set with a slide rail that matches the slot. After the convex strip is slidably connected to the slide rail through the slot, it is fixed at both ends of the slide rail with positioning pins to ensure that the convex strip is vertical and stable, and can also be disassembled or easily maintained.

[0017] The protruding height of the convex strip is 20-30cm, the cross-section is semi-circular or trapezoidal, the surface is smooth and without sharp edges, and polyurethane sandwich panels are used to ensure compatibility with the overall structure of the cold storage.

[0018] The beneficial effects of this utility model are as follows:

[0019] By adopting the structure of this utility model, the airflow blown out by the top-mounted cold air fan, combined with the convex strips, can preferentially absorb the heat leakage transmitted from the cold storage panels, preventing heat conduction to the goods, improving the stability and uniformity of the cold storage temperature. The convex strips effectively isolate the goods from the wall panels and form airflow channels on the wall, avoiding dead corners and turbulence in the cold storage, and preventing cold air from blowing directly onto the goods, reducing the dryness loss of the goods. The arc-shaped panels eliminate the right-angle structure at the corners, preventing the generation of airflow vortices, reducing airflow kinetic energy loss, and eliminating sanitary dead corners, making it easier to clean and maintain the cold storage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 2-4 As shown, a cold storage airflow guiding structure includes a cold air blower 2, an arc-shaped plate 4, and a convex strip 5. The cold air blower 2 is installed in the central area of ​​the ceiling at the top of the cold storage 1 or is evenly distributed along the length of the ceiling, and its air outlet direction is parallel to the bottom surface of the ceiling. The arc-shaped plate 4 is installed at all the corners of the walls inside the cold storage 1. The convex strip 5 is vertically embedded in the inner side of the wall panel inside the cold storage 1 and is evenly distributed along the height of the wall panel.

[0027] Air cooler 2 can be an ultra-thin air cooler: it can use a stainless steel shell, and is equipped with a low-noise fan inside. Its air outlet is flat and the thickness is controlled at 12cm. The width of the air outlet is set according to the width of the ceiling of cold storage 1. For example, a 10m wide cold storage 1 corresponds to an air outlet width of 8m and an air outlet height of 4cm. The flange is made of 8mm thick stainless steel plate and has reserved bolt holes.

[0028] The curved plate 4 can be made of 304 stainless steel plate, bent into shape, with an arc radius of 10cm and a plate thickness of 4mm. The length is cut according to the length of the corner of the cold storage 1 wall. Ear plates can be welded to both ends of each plate, and bolt holes are reserved in the ear plates.

[0029] The convex strip 5 can be integrally molded from polyurethane sandwich panels, with a semi-circular cross-section and a protrusion height of 25cm. The length of the convex strip 5 extends from the floor surface to 3-5cm below the bottom surface of the ceiling. The spacing between adjacent convex strips 5 is 80-120cm. The protruding direction of the convex strip 5 faces the inside of the cold storage 1. The minimum distance between the protruding end and the goods shelf is controlled at 15-20cm. A slot can be provided on the back (not shown in the figure). The wall panel can be pre-set with a sliding rail for snapping. This is an existing structure.

[0030] In addition, the air outlet of the air cooler 2 can be equipped with adjustable guide vanes. The guide vanes are the existing structure and will not be described in detail here.

[0031] Cold storage unit 1 can be pre-installed with stainless steel mounting brackets on the ceiling, spaced 2m apart, and fixed to the ceiling with expansion bolts. Air cooler 2 can be fitted with a flange aligned with the mounting brackets, and after placing a sealing gasket, secured with bolts to ensure that air cooler 2 is installed horizontally and that the airflow direction is parallel to the ceiling.

[0032] Install curved plates 4 at all corners of cold storage 1. The ear plates of the curved plates 4 can be welded and fixed to the pre-embedded steel parts, and then reinforced from the outside with expansion bolts. After welding, the joints of the plates are polished smooth.

[0033] Insert convex strips 5 along the inner slide rail of the wall panel (not shown in the figure) at intervals of 100cm.

[0034] After installation, turn on the air cooler 2. The airflow blown out by the air cooler 2 at the top, combined with the convex strip 5, can preferentially absorb the heat leakage from the cold storage panel, prevent heat conduction to the goods 3, improve the stability and uniformity of the cold storage temperature, and the convex strip 5 effectively isolates the goods 3 from the wall panel and forms an airflow channel on the wall, avoiding dead air and turbulence in the cold storage 1, and preventing the cold air from blowing directly on the goods 3, reducing the dryness loss of the goods.

[0035] The curved panel 4 eliminates the right-angle structure at the corner, thereby avoiding the generation of airflow vortices, reducing airflow kinetic energy loss, and eliminating sanitary dead corners, making it easier to clean and maintain the cold storage 1.
